The invention discloses a double-color rubber mat at the front end of an automobile auxiliary instrument board and a preparation method of the double-color rubber mat. The double-color rubber mat comprises a black rubber layer of a square structure and a red rubber layer located in the center of the black rubber layer. The black rubber layer and the red rubber layer are formed by integral injection molding. The black rubber layer is prepared from the following raw materials in parts by weight: 40-50 parts of TPS thermoplastic elastomer, 10-15 parts of PP, 5-8 parts of paraffin-based filling oil, 5-12 parts of diatomite, 3-5 parts of an impact modifier, 5-10 parts of a binder, 12-15 parts of a phosphorus/nitrogen/silicon ternary composite flame retardant, 1-8 parts of a flame retardant synergist and melanin. The double-color rubber mat has the advantage that the flame retardance is improved.

    本发明公开了一种汽车副仪表板前端双色胶垫及其制备方法,包括方形结构的黑色橡胶层以及位于黑色橡胶层中心部分的红色橡胶层,所述的黑色橡胶层以及红色橡胶层通过一体注塑而成,所述的黑色橡胶层包括按照以下份数配比的原料:TPS类热塑性弹性体40‑50份、PP10‑15份、石蜡基填充油5‑8份、硅藻土为5‑12份、抗冲击改性剂3‑5份、粘结剂5‑10份、磷/氮/硅三元复合阻燃剂12‑15份、阻燃协同剂1‑8份和黑色素。本发明具有提高阻燃性的优点。
